PROCESS OF RECONSTRUCTING RAILROAD-RAILS.

SPECIFICATION formingpart of Letters Patent No.-700,063, dated May 13, 1902.

Application filed January 6, 1902, Serial No. 88,542. (No model.)

citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Process of Reconstructing Railroad-Rails, of which the following is a full, clear, and exact description.

The object of my invention is to enable the ordinary flanged or Johnson rail to be conveniently and cheaply transformed into a grooved rail without taking the rail up from the tracks. This end I attain by first swaging or upsetting the edge of the flange of the rail and thenrunning the metal into a mold which extends along the flange of the rail and into which the flange projects, so that when the mold is removed the rail is left witha second tread or bead running alongside the ball of the rail and forming the groove therein.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the rail, showing the first step of the process.

position. Fig. 2.

Fig. 3 is a section on the line 3 3 of Fig. at isa section on the line 4 L-of Fig. 3, and Fig. 5 is a perspective view of a" completed or reconstructedrail. .c

Ct indicates the rail, and bthe flange thereon, these being ofthe usuafform according to the well-known flanged or Johnson rail. The first act necessary is to swage down or down-set the flange, as indicated'at b. The

when the metal is run into the cavity a tread or bead a, Fig. 5, will be formed correspond-" ing with the principal tread or ball of the rail.

The mold is provided with a number of gates 0 which may be'of'any number and form, as

desired, and through which the metal is run into the mold. Formed longitudinally along one side'of the mold is a slot 0 the walls of which taper inward, so that the flange b of the rail may be wedged into this slot, the outer Fig.2 is a side View of the rail, showing the mold in edge of the flange lying about in the longitudinal center of the cavity of the mold. This slot 0 according to the construction here shown, is formed by separating the adjacent walls of the two sections of the mold, so that when these sections are placed together, as in Fig. 1, the walls at the side adjacentto the rail will be apart from each other, thus forming the slot. The mold-sections are held together by studs 0 and keys 0 The upper inner wall of the mold is ribbed transversely, as at c, to form the grooves in the second bead at, (indicated at (1 in Fig. 5.) The mold is' placed in position, as in Fig. 3, and the metal is run into the mold through the gates and sets around the flange, thus forming the rail with the second tread orbead, as before described, and producingthe groove, as at b in Fig. 5. When this is effected, the mold is removed from the rail by disconnecting the mold-sections. The mold-sections are placed on the rail'when the same is in place as part of the track. A portable cupola is employed in connection With the mold, and thus the reconstruction of the rails may be carried on along the length of the railway as contradis- .tinguished from in a mill or factory provided for that purpose.

The swaged or down-set portions b of the edge of the flange b servetofirmly unite the vsecond tread a with theflange b and prevent any displacementof thesecond tread after the metal has harden'edon the flange.

Having thus described my invention, I claim as new and desire to secure by Letters .Patent- 1. The process of transforming flanged rails into grooved rails while in position on the road-bed, which consists first in swaging or oifsetting the edge of the flange of the rail, and then casting a strip of metal on the flange parallel to the ball or tread of the rail.

2. The process of transforming flanged rails into'groOvedfrails, while in position on the road-bed,which consists in first swaging or offsetting the edge of the flange of the rail at .one or. more parts to form'projecting portions at said edge, second, protecting the portion of the flange adjacent to the tread, =tl 1i'rd,running a mass of molten metal along the unprotected outer portion of the flange and paral lei to the ball or tread of the rail, and allow- I name to this specification in the presence of ing the metal to harden on the flange, there- I two subscribing witnesses. by forming a second tread spaced from the tread of the rail to produce the groove, the 5 swaged or offset portion of the flange serving to retain the second tread in position.

In testimony whereof I have signed my VERNON T. LYN CII.
